Technical field
The present invention relates to be installed on the glass run of the doorframe inner rim of motor vehicle automobile door, this glass run is used to guide the car door glass lifting.
Background technology
As shown in Figure 1, glass run is installed on the inner rim of the doorframe 12 of car door 14, and this glass run is used to guide automobile door glass 16 liftings.Fig. 2 is the sectional view along A-A line among Fig. 1, and shows the mounting structure that glass run 10 is common.
As illustrated in fig. 1 and 2, usually, glass run 10 is coupled in the guide groove 40 that is formed in the doorframe 12, with 16 liftings of guiding automobile door glass, and provides sealing between automobile door glass 16 and the doorframe 12.Glass run 10 is connected by bight 20 to be extruded straight portion 18 and forms, extrude straight portion 18 and be fit to along the upside of car door 14, preceding vertical side and the vertical installation in back, each bight 20 by mould-forming for to conform to the turning of doorframe 12.
Door weather strip 22 is installed on the neighboring of doorframe 12, and opening trim weather strip 24 is installed on the flange that is arranged in the vehicle body door opening portion, formation sealing between car door 14 and vehicle body thus.
As shown in Figure 2, glass run 10 comprises lateral wall 26, inside wall 28 and diapire 30, and glass run has roughly U type cross section.Outer seal lip 32 and interior sealing lip 34 are extended in glass run 10 by the openend of lateral wall 26 and inside wall 28 respectively.And respectively, along the external surface of lateral wall 26 and inside wall 28, enclosing cover lip 36 and inner cap lip 38 are extended towards diapire 30 by the openend of lateral wall 26 and inside wall 28.
In the time of in automobile door glass 16 enters glass run 10, the neighboring of automobile door glass 16 is by outer seal lip 32 and 34 sealing and the clampings of interior sealing lip.
When automobile door glass 16 rose to fastening position, the upper end of automobile door glass 16 upwards pushed away the diapire 30 of glass run 10.During this time, diapire 30 does not absorb moving up of automobile door glass 16 fully, thereby the upper end of automobile door glass 16 causes reducing the noise of driving comfort via diapire 30 pushing guide grooves 40.When the upper end of automobile door glass 16 pushing diapire 30, diapire 30 distortion cause the upper end of automobile door glass 16 to depart from the displacement of regulation fastening position, thereby sealing lip 32 and 34 may cause sealing performance to reduce by undesirable deformation.
Thus,, tube is set in diapire in order to absorb moving up of automobile door glass, or sponge member is attached on the diapire (referring to, for example not unexamined patent communique No.Hei8-318740 and do not examine utility model No.Sho 62-413).As shown in Figure 3,, adopt the hollow extrusion method usually on diapire 30 for tube 46 is set, but in extrusion in order to keep the air pressure in the tube 46, need high-caliber pressure control.Therefore, keep the shape of tube 46 very difficult, and improve equally very difficulty of extruded velocity, can't obtain higher production efficiency thus.When sponge member is attached to diapire, the sponge member of big thickness can not be set in the crawl space between diapire and the doorframe, can't obtain enough bump absorbabilities thus.On the other hand, if the thick sponge member of use increases the bump absorbability, the stability of diapire with respect to doorframe will be reduced.

As shown in Figure 4, the straight portion 48 that extrudes of glass run 10A comprises lateral wall 62, inside wall 64 and diapire 66.Outer seal lip 68 and interior sealing lip 70 extend to glass run 10A inside by the openend of lateral wall 62 and inside wall 64 respectively, thereby when glass run 10A was installed on the doorframe 12, sealing lip 68 and 70 top were in contact with one another.
Diapire 66 comprises middle part 74, outside portion 76 and inside portion 78, and the outside portion is connected to lateral wall 62, and the inside portion is connected to inside wall 64.The middle part 74 of diapire 66 has tabular cross section, and the glide directions that outer half part in middle part 74 is basically perpendicular to automobile door glass 16 extend (Fig. 5), and in it half part inwardly sidewall 64 swell gradually.And shock absorbing lip 84 and projection 86 be half part inner and sidewall 64 diagonally extendings inwardly towards glass run 10A respectively in 74 from the middle part.
The outside portion 76 of diapire 66 extends upward and is connected by the thin-walled connecting portion with the bottom of lateral wall 62.The inner surface of outside portion 76 forms flat condition, and facing to lateral wall 62.When glass run 10A is installed on the doorframe 12, lateral wall 62 is easily along the bending of thin-walled connecting portion, make glass run 10A insert doorframe 12 easily, and when the upper end of automobile door glass 16 pushes away the middle part 74 of diapire 66 by shock absorbing lip 84, outside portion 76 is easily along the bending of thin-walled connecting portion, cause middle part 74 bendings, therefore absorb the impact that automobile door glass 16 pushing diapires 66 cause.
Sealing lip 80 is tilted to protrude upward by the upper end of outside portion 76, and by middle part 74, outside portion 76 and the inside portion 78 of diapire 66, limits recess 72.
Buffer unit 82 is made of cavernous body, has roughly non-circular cross-section, by with its stickup or be fused to the external surface of diapire 66, makes it be fixed in recess 72.
And outer lip 88 and epipharynx 90 are arranged at lateral wall 62 and inside wall 64 respectively, are used to make glass run 10A firmly to be installed to doorframe 12.
When the glass run 10A of structure like this is installed on the channel guide section timesharing of doorframe 12, outer lip 88 and epipharynx 90 are coupled to respectively in the step that is formed at doorframe 12 guide grooves part, are used to prevent that glass run 10A from partly being deviate from by the guide groove of doorframe 12.And provide the sealing between glass run 10A and the doorframe 12.
The upper wall of doorframe 12 guide grooves part relaxes upwards protuberance of inclination mode.When glass run 10A is installed on the channel guide section timesharing of doorframe 12,, limit and have the space that is the general triangular cross section that outwards increases gradually by the upper wall of guide groove part, the middle part 74 and the upwardly extending outside portion 76 of diapire 66.Therefore, can use buffer unit 82, improve impact absorption power for automobile door glass 16 with big thickness.In addition, by means of the general triangular space, follow the bending of outside portion 76, middle part 74 produces very big being bent upwards, thereby thick buffer unit 82 is with easy deformation.
As shown in Figure 5, in the time of in automobile door glass 16 enters glass run 10A, the top of outer seal lip 68 and interior sealing lip 70 contact its peripheries from two surfaces of automobile door glass 16, so that it is sealed, and the last end in contact of automobile door glass 16 and bending shock absorbing lip 84.As a result, the impact that is caused by automobile door glass 16 contacts can be absorbed by shock absorbing lip 84.
Preferably, shock absorbing lip 84 is with the mode bending towards the opening projection of glass run 10A.
When the upper end of automobile door glass 16 pushing shock absorbing lip 84, shock absorbing lip 84 bendings, and the inner surface at its contact diapire 66 middle parts 74, top, thus define cavity with arciform cross section.Pushing crooked shock absorbing lip 84 in the upper end of automobile door glass 16 makes it towards the cavity bending, has therefore absorbed the impact that the promotion by automobile door glass 16 upper ends causes.
When automobile door glass 16 further rose, the outer end at the top of shock absorbing lip 84 pushing diapire 66 middle parts 74 made middle part 74 78 be bent upwards along the inside portion.As a result, be fixed in buffer unit 82 distortion of diapire 66 external surfaces.Thus, the crooked step by step or distortion of shock absorbing lip 84, diapire 66 and buffering parts 82, the impact that causes with the promotion of guaranteeing to absorb by automobile door glass 16 upper ends, and therefore, prevent the generation of noise.
In addition, when buffer unit 82 contact doorframes 12, the sealing lip 80 of the outside portion 76 of diapire 66 also contacts with doorframe 12, therefore absorb the impact that the promotion by automobile door glass 16 upper ends causes, and the sealing performance between reinforcing glass chute 10A and the doorframe 12, and therefore, prevent the generation of noise.
At this moment, on the inner surface of shock absorbing lip 84, sliding towards lateral wall 62 in the upper end of automobile door glass 16, and closely contacts outer seal lip 68, therefore strengthened the sealing performance between automobile door glass 16 and the outer seal lip 68.In addition, can reduce the difference that flushes between automobile door glass 16 and the doorframe 12.
In addition,, can firmly keep glass run 10A, and therefore, when automobile door glass 16 pushes the diapire 66 of glass run 10A, can prevent that glass run 10A from sliding in doorframe 12 because the outside portion 76 of diapire 66 all contacts with doorframe 12 with buffering parts 82.
And the flat inner surface of outside portion 76 closely contacts lateral wall 62, topples over towards glass run 10A inside to prevent lateral wall 62.On the other hand, projection 86 contacts are also supported inside wall 64, topple over towards glass run 10A inside to prevent inside wall 64.
Inside wall 64 and interior sealing lip 70 form bigger and thicker than lateral wall 62 and outer seal lip 68 respectively.By this structure, automobile door glass 16 can be to outside fix, thereby has reduced the difference that flushes between automobile door glass 16 and the doorframe 12.Therefore, reduced air resistance, reduced the generation that wind is made an uproar, and improved aesthetic appearance.
Shock absorbing lip 84, outer seal lip 68 and interior sealing lip 70 are towards surface-coated low sliding resistance material, for example polyurethane resin, the silicones etc. of automobile door glass 16.When automobile door glass 16 liftings, can reduce the sliding resistance of automobile door glass 16, avoiding the generation of noise, and prevent that glass run 10A from sliding from predetermined installation site.
In addition, sealing lip 68 and 70 is similar with putting on, and the material with low sliding resistance is applied in the inner surface of diapire 66, can reduce the sliding resistance of shock absorbing lip 84 and diapire 66 thus.Material with low sliding resistance can be put on the inner surface of lateral wall 62 and the rear surface that outer seal lip 68 faces toward lateral wall 62.By this layout, can prevent that outer seal lip 68 from pasting on the lateral wall 62.
In the accompanying drawings, number designation 92 indicates the enclosing cover lip that is used to cover doorframe 12 outer ends, and number designation 94 indicates the inner cap lip that is used to cover doorframe 12 interior angles.
Below, with reference to Fig. 6 the second embodiment of the present invention is described.Glass run 10B and the glass run 10A among first embodiment of second embodiment are similar.Therefore, emphasis is described the part that present embodiment is different from first embodiment, and similarly partly will use identical numeral with first embodiment.
As shown in the figure, the diapire 96 of glass run 10B comprises middle part 98, outside portion 100 and inside portion 102.The middle part 98 of diapire 96 has tabular cross section, and is basically perpendicular to the extension of automobile door glass lifting direction.The outside portion 100 of diapire 96 extends upward respectively with inside portion 102 and is connected lateral wall 62 and inside wall 64, having roughly U type cross section, and limits recess 104 by outside portion 100, middle part 98 and the inside portion 102 of diapire 96.
When glass run 10B was installed on the doorframe 12, respectively, outside portion 100 and inside portion 102 were all further crooked, cause contacting the guide groove upper wall partly of doorframe 12, therefore firmly keep glass run 10B.Under the installment state of glass run 10B, the upper wall that the middle part 98 of glass run 10B is basically parallel to the guide groove part extends, thereby recess 104 has rectangular cross section roughly.
And, from the middle part 98 with the connecting portion of inside portion 102, shock absorbing lip 107 and projection 108 be inner and sidewall 64 diagonally extendings inwardly towards glass run 10B respectively.

Shock absorbing lip 118 is with the mode bending towards the opening projection of glass run 10C.Projection 124 forms along the top of shock absorbing lip 118, thereby outstanding towards diapire 110.
As shown in Figure 8, when the contact impact absorbing lip 118 of the upper end of automobile door glass 16, shock absorbing lip inner surface bending of 112 towards the middle part, and the inner surface at the projection 124 contact middle parts 112 of shock absorbing lip 118 also slides thereon, thereby engage with the protuberance 122 at the middle part 112 of diapire 110, therefore define the tube of arciform cross section.When the upper end of automobile door glass 16 promotes crooked shock absorbing lip 118, the slip of the shock absorbing lip 118 under this state is stopped by protuberance 122, shock absorbing lip 118 is further crooked, make the tube between shock absorbing lip 118 and the diapire 110 be out of shape, therefore the situation when the top of shock absorbing lip does not engage with diapire has absorbed the impact that the promotion by the upper end of automobile door glass 16 causes biglyyer.
Then, the production method of glass run is described with reference to the glass run 10A among first embodiment according to the present invention.
Straight portion 48 and the bight 50 of glass run 10A are made up of the compact material of synthetic rubber, thermoplastic elastomer (TPE) or soft synthetic resin, and synthetic rubber is EPDM rubber, thermoplastic elastomer (TPE) olefin elastomer, soft synthetic resin soft vinyl chloride etc. for example for example for example.
Straight portion 48 extrudes compact material by extruder and forms, and the material of extruding is cut to predetermined length.
Under the synthetic rubber situation, after extruding, baking in the curing cage of hot air, high frequency waves etc., and under thermoplastic elastomer (TPE) or soft synthetic resin situation, cooling curing.Then, by applying or pasting, low slip resistance material is put on the surface of outer seal lip 68, interior sealing lip 70, shock absorbing lip 84 and diapire 66.
Then, be placed in the mould by the end that will extrude straight portion 48, and compact material is expelled to mould cavity, form bight 50.The bight 50 of molding has and each roughly same cross section of straight portion 48.Preferably, the material of molding portion use is similar with the material that extruding part uses.Under thermoplastic elastomer (TPE) or soft synthetic resin situation, the material that molding portion is used is molten condition when injection, and heat and pressure by this material are fused to molding portion on the extruding part.
Under the synthetic rubber situation, be injected into mould after, heating mould is so that synthetic rubber sulfuration.Because sulfuration can form integral body by extruding part and the molding portion that same material or same type of material constitute.Under the situation that extruding part is made up of synthetic rubber, molding portion can be made up of thermoplastic elastomer (TPE).
